South Platte, North Platte, & Platte Rivers Prolonged Flooding
 
Above normal precipitation in the Rocky Mountains during late winter and early spring of 2015 resulted in well above normal snow pack in the headwaters of the North Platte River and the South Platte River. Above normal precipitation continued for the late spring and early summer months across the entire region. In addition to the above normal mountain snow was cool spring temperatures, which delayed the snow melt. The combination of the delayed snow melt and above normal rainfall resulted in portions of the South Platte River, North Platte River upstream of Lake McConaughy, and the Platte River seeing prolonged flooding starting in May, cresting in June, and for some isolated areas lingering into early July. Fortunately, Lake McConaughy was able to absorb the high flows preventing flooding downstream on the North Platte River and adding to the flooding on the Platte River.

Severe Storms Strike Along the Highway 83 Corridor on August 13th
 
Thunderstorms developed in the central sandhills during the late afternoon hours on August 13th. Storms quickly became severe as they tracked along highway 83 from Thedford to south of North Platte during the evening hours. Tennis ball sized hail and 60 mile per hour wind gusts were reported across Thomas, Logan and northern Lincoln County. As the storms approached North Platte, they intensified producing 60 to 70 mile per hour winds, golf ball sized hail and up to an inch of rain which fell in 20 minutes. The 60 to 70 MPH winds led to severe tree damage across central and western portions of North Platte. Numerous power outages were reported, and across portions of southwest North Platte, power outages extended well into the following day. Severe storms continued south before weakening in Frontier County.
